Property taxes and your closing

When you buy or sell property in Castro County, property taxes are prorated at closing based on the transaction date and contract terms. Your title company will review Castro County tax records for delinquencies, pending liens, and open protests that could affect title.

File homestead and other exemption applications with the Castro County Appraisal District after closing if you qualify. Exemptions are not automatic — they require an application on the CAD's timeline.

Use the county appraisal district property search to verify the parcel, current owner, and appraised value before closing. Discrepancies between contract value and tax roll data should be resolved early in the transaction.
